### Please describe the problem.

Running `git add` or `git annex add` does not add dotfiles to the annex. However, the git annex assistant appears to add dotfiles to the annex.

### What steps will reproduce the problem?

1. Initialize a new repository (`git init` and `git annex init`).

2. Create a dotfile: `echo "foo" > .somedotfile`

3. Run `git annex assistant`

The file will then be added to the annex.

### What version of git-annex are you using? On what operating system?

Operating system: Arch Linux x86_64

git-annex version: 10.20230329

### Please provide any additional information below.
